Microstructural and biochemical characterization of the nanoporous sucker rings from Dosidicus gigas
Recent interest in the development of environmentally benign routes to the synthesis of novel multifunctional materials has resulted in numerous investigations into structure-function relationships of a wide range of ...
Entropy-driven formation of a chiral liquid-crystalline phase of helical filaments
(American Physical Society, 2006-01-11)
We study the liquid-crystalline phase behavior of a concentrated suspension of helical flagella isolated from Salmonella typhimurium. Flagella are prepared with different polymorphic states, some of which have a pronounced ...
Long-term ecological research in a human-dominated world
(American Institute of Biological Sciences, 2012-04)
The US Long Term Ecological Research (LTER) Network enters its fourth decade with a distinguished record of achievement in ecological science. The value of long-term observations and experiments has never been more important ...
Chlorophyll fluorescence tracks seasonal variations of photosynthesis from leaf to canopy in a temperate forest
Accurate estimation of terrestrial gross primary productivity (GPP) remains a challenge despite its importance in the global carbon cycle. Chlorophyll fluorescence (ChlF) has been recently adopted to understand photosynthesis ...
Saltmarsh plant responses to eutrophication
(John Wiley & Sons, 2016-10-20)
In saltmarsh plant communities, bottom-up pressure from nutrient enrichment is predicted to increase productivity, alter community structure, decrease biodiversity, and alter ecosystem functioning. Previous work supporting ...
Neuronal calcium sensor-1 enhancement of InsP3 receptor activity is inhibited by therapeutic levels of lithium
(American Society for Clinical Investigation, 2006-06)
Regulation and dysregulation of intracellular calcium (Ca2+) signaling via the inositol 1,4,5-trisphosphate receptor (InsP3R) has been linked to many cellular processes and pathological conditions. In the present study, ...
Processing arctic eddy-flux data using a simple carbon-exchange model embedded in the ensemble Kalman filter
(Ecological Society of America, 2010-07)
Continuous time-series estimates of net ecosystem carbon exchange (NEE) are routinely made using eddy covariance techniques. Identifying and compensating for errors in the NEE time series can be automated using a signal ...
Burn severity influences postfire CO2 exchange in Arctic tundra
(Ecological Society of America, 2011-03)
Burned landscapes present several challenges to quantifying landscape carbon balance. Fire scars are composed of a mosaic of patches that differ in burn severity, which may influence postfire carbon budgets through damage ...
Envisioning a marine biodiversity observation network
(University of California Press, 2013-05)
Humans depend on diverse ocean ecosystems for food, jobs, and sustained well-being, yet many stressors threaten marine life. Extensive research has demonstrated that maintaining biodiversity promotes ocean health and service ...
Correction to “Importance of carbon-nitrogen interactions and ozone on ecosystem hydrology during the 21st century”
(American Geophysical Union, 2009-08-22)
